Going through a box of floppies to check which still work and which don't. I'll keep just a few working ones to work in the Amiga and Alpha, dump the bad ones and donate the remaining working ones to Re-PC.

It is 2026 and glibc's longjmp still doesn't execute finalizers when truncating the stack.

@firefox.com is a great PDF reader. It can sync the TOC and navigate hyperlinks just fine. It can deal with the Arm ARM's 102 MiB file much better than Adobe's own reader which is a resource hog and is always trying to sell you something.

Q: "Hey Siri, what is the driving distance between Tacoma and Kirkland both in Washington". A: "I need to know your location. Please enable Siri access to location on your settings app." So... why do you need my current location to answer that question?

.NET Lab can now display disassembled machine code. It's taken directly from JIT, hence only supported on desktop for now. #dotnet #csharp #roslyn #asm #dotnetlab

Good news. In VS 2026 Preview /Oy- is now the default, even in the "Release" configuration. This is the case at least for new projects. Glad to see this finally fixed.

Now this is something unexpected: Tahoe's new "Apps" pannel behaves worse than Windows start menu. It is sluggish, at times downright unrespinsive, some UI elements just don't work... it is me or "26" is just not Apple's number?!

When there are all adults in an adult setting it is weird to ask where the "potty" is. You ask for the "bathroom", or some other adult word for it. Same goes for an engineer to say "BSOD". The word is "Bugcheck".

Intel's 386 processor (1985) moved the x86 architecture to 32 bits, but it needed to be backward compatible with earlier 16 and 8-bit processors. As a result, it needed complicated circuitry for its internal registers: six different circuits for 30 registers. Let's look at the silicon circuits. 1/N
A die photo of the Intel 386 processor under the microscope. The die has complex patterns that make up the different parts of the chip. The various blocks are roughly rectangular with different textures.
The main functional blocks are labeled, including the paging unit, bus interface unit, prefetch unit, segment unit, instruction decode unit, protection test unit, data unit, and control unit. The register file, the subject of this thread, is in the lower left corner, highlighted by a red rectangle. This die photo image has a purple tint.

Added a way to diff two assemblies at the byte level. This is what I really needed it for - to debug deterministic builds. I needed to see why is the assembly different even though nothing has changed. In this case it was SourceLink stamping the Git SHA into the embedded pdb.
Screenshot of an assembly diff tool, the tree on the left shows the PE file structure and metadata, hex editor on the right shows changed bytes.
